7 IQ appertains to make and use the same.

My invention has reference to whiffletree attachments, and has for its object to provide simple and strong means for attaching the.

singletree to the doubletree'or the latter to r the tongue, so that no boltsor nuts will be necessary, and so that the two parts composing the attachment will each be made in one piece, and, besides forming the attachment,

will also serve to strengthen the single and,

double trees.

' To the accomplish iuent of the foregoing ends and such other results as may follow from the construction theinvention consists in the combination'of parts hereinafter particularly described and claimed, reference being bad to the accompanying drawings, forming a part hereof, and inwhioh- I Figure 1, is a front view of a singletree attached by the improved'means to a portion of 0 a doubletree. Fig.2 is aperspective'of the.

same parts detached from each other;

In the drawings, the letter A designates a bar or doubletree formed with a hole, B, passing through it,'in the wall of which are formed I 5 the slots at, of which there may be only one,

although two are shown. This doubletree is clasped by a band, 0, which is slipped over the doubletr'ee, andwhich is formed in its upper and lower faces with openings or holes 0 D, in the walls of eachof which are formed slots 1), one or more, corresponding to the hole and slots in the doubletree. This band is also formed with a boss, E, on its top face,'which serves, among other things, to afford a broad and firm bearing for the second part of the attachmeutrsecured to'the'singletree. The

band is also provided with the loop F for the stay-strap. v The bolt G, which pivots the singletree I to "5o the doubletree, is formed in one piece with the ring or band H,which encirclesthe singletree, and is formed at its lower, end with a laterally-projectingpin or pins, 0; which nor 'mally set at a right or other angleto the slots formed in the doubletreeand its band, so that '55 when in that position the parts will be pivot ally locked together, but'which, 'whenfthebolt is turned to bring thepin in linewith the slots,will permit the singletreefand double tree to be unlocked and separatedor attached 6o together. Under the construction shown it is necessary to turnthe singletree one-quarter around before it can be detached ,from'the doubletree, and as that will never happen when the horse is traced to the vehicle itis plain that the parts cannot become accidentally separated. Between the boss of the doublev tree-band and'the'ring or band of the single. tree is a plate or leaf, 1, formed integral with the bandH audbolt Gand bearing on the boss 7:

of the doubletree-band, the boss and the plate 7 taken together forming two leaves bearing against each other and forming a strong hearingand brace, one for the'other, and keeping the connection between the two trees firm and 7 5' r v steady.

The singletree is secured to the band H I forcing the same into the ban'd'and is held se- I curely in place by the band. It will appear also that no hole need be bored through the so singletree to secure it in-place,\andflconsequently it is stronger than when otherfwise made. It isalso apparent that no bolts, screws,

or nails are necessary to secure any of the a parts together, and that they are easilyapplied and form astrong, durable, and efficient attachment for the purposes described.

' The attachment, as previously intimated, can be used for attaching the doubletree tothev tongue in the same manner that one tree is attached to the other, and its application is not confined to any particular kind of vehicle,

Havingdescribed my invention and set forth its merits, what I claim is-- l 1. The bar or doubletre'eband formed with 9 a hole through it having a 'slotin its wall, in combination with the singletree-band having 1 formed rigidly therewith a bolt provided with a lateralpin adapted to pass "through ',the

apertured band when the pin is n line with its slot and to pivotally lock the two bands together when turned out of line with the slot, substantially as described.

2. The barror doubletree band formed with a boss or leaf on one face and a slotted aperture, in combination with the singletree band provided with a bolt formed integrally therewith, having a lateral pin and a leaf below the band, whereby the two bands may be pivotally locked together and have a firm connection one with the other, substantially as described.

3. The combination of the bar or doubletree, formed with the hole through it, having a slot in its wall, the band to encircle said tree,
